Abstract of the project-team:

The objective of this team is the ultra-low power consumption of electronic circuits. To do that we suggest to study non-uniform event-driven sensors/actuators and parsimonious signal processing in systems. More precisely, one of the objectives is to develop a low-power vision sensor. Such an electronic circuit will be designed at the very beginning of the project. The second theme is about the optimal control of systems equipped with converters. It asks to study non-smooth dynamical systems. For nonlinear control systems, the possibility of updating the control inputs, only when some events occur, will be also investigated. Thus the observation and the control of event-based dynamical systems will be also studied. These events may come from a function of the state or of the measured output only. Finally two demonstrators will be built to illustrate and combine all results obtained in the project. For all axis, optimization objectives will be tackled, as the minimization of numbers of level-crossings that are necessary to recover a signal in a given class of signals.

The applications that we have in mind are embedded systems with ultra-low consumptions. More precisely, the applications include event-driven architectures, as micro-electronic components. The practical applications are medical ones, and minimization of electrical consumption for networks systems. The applications of the event-triggered controls for nonlinear systems, or for non-smooth systems are the control of biomimetic robots (as micro flying artificial insects) and mechanical systems with constraints of first or second order (as the control of dynamical objects with shocks and constraints on the state variables).

This team is supported by the themes Modeling and Simulating the physical world (SIM) and Pervasive Computing Systems (PCS) of Persyval-lab.
